I don't know if that is factually correct. Some of the bug reports seem
to indicate that it was "fixed" by just not adding the new Jordan rule.
I haven't tested against any proprietary releases to confirm this
though.

But this one is indeed identical to my fix.

Note that the testcase you include doesn't show the bug unless you also
update the tzdata. The IcedTea6 patch includes a test case that shows
the bug independent from the tzdata used.
